California agriculture officials reported good news for wine lovers and vineyard operators alike: a record harvest of wine grapes.

Growers in the nation’s premier wine region brought in a productive harvest last year, thanks to expanded acreage and overall favorable weather.

Wine brokers told The Modesto Bee that two back-to-back years of large harvests will mean wine aficionados should find plenty of bargain bottles on grocery store shelves.

“Consumers are in a great position because of the amount of wine that is coming out of California,” said Erica Moyer of Riverbank, a grape and wine broker for Turrentine Brokerage in Novato.

Wine grapes are one of California’s top commodities, a crop worth $3.16 billion last year, according to the California Association of Winegrape Growers.

The California Department of Food and Agriculture’s preliminary figures show that the crop of red and white varieties combined weighed in at 4.23 million tons in 2013, up 5 percent from 4.02 million tons in 2012.

The industry is well positioned to take advantage of the large crops, said Heidi Scheid, chairwoman of the winegrape growers’ association.

“After short crops in 2010 and 2011, growers delivered two remarkable vintages, with record-sized harvests and exceptional quality,” she said.

While Napa County’s vineyards carry international cache, the San Joaquin Valley, stretching for 220 miles from Stockton to Bakersfield, is the U.S.’s most prolific grape-growing region and home to 44 percent of the state’s crop.

Along with raisins and table grapes, vast tracts of wine grapes are mechanically harvested for popular labels such as Gallo’s economy brands and Bronco’s popular Charles Shaw, aka Two Buck Chuck, and blended into higher end wines.

Large growers in the valley are poised to profit from the higher volumes, analysts said.

“We had a good-quality harvest, and heavier than expected,” Fred Franzia, CEO of Bronco, said in an email. Bronco is California’s largest vineyard owner.

The Denver Art Museum plans to funnel a $25 million one-time gift into the estimated $150 million budget for renovating its iconic North Building in time for the structure’s 50th anniversary in 2021, officials announced Thursday.
